thanks, Dr. Henry

and other people here.

Interesting to read your last paragraph. Have you ever heard of such things happened? Say if by accident a mole got scrached or scraped (by dog maybe) and bleeded, then it has risk by turning into skin cancer?

I know in medicine you never say never. Like doctor always say that anything is possible. But should it be a reason for anything that could happen?

I don't have much knowledge in medical area. I think human body is so complicated and amazing, you never know what will grow in your body. Now I am kind of becoming cancer phobia, suspicious about anything that could become cancer.
